IMPROVEMENT IN GULTIVATORS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I,'A. H. ALLISON, of Oharlottesville, in the county ofHancock, and State of Indiana, have invented'certain new and usefulImprovements in Cultivators; and I do hereby declare that the followingis afull, clear, and exact description thereof, reference being bad tothe accompanying drawings, and to the letters offreference markedthereon, which form a part of this specification, and in which- 'Figure1 represents a side elevation, and I Figure 2 a plan or top view of mycultivator.

The nature of this invention consists inthe construction and'arrangementof certain devices, the peculiarities of which willbe hereinafter setforth.

To enable others skilled in the art-to which my invention appertains tomake and use the same, I will now describe its construction andoperation.

In the accompanying drawingsv A represents aframe, to which are securedthe axles, (see fig. 2,) upon which the wheels B B are situated.Secured" across frame A, near its front end, is a bar or support, 6, tothe rear side of which are secured hooks d d, to be referred tohereafter. Theztongue D is secured to the under side of the front bar offrame A and brace b. To the tongue I), on the inside of said frame, issecured the double-tree c, which is provided with two arms, 0' c,projecting out therefrom a. suitable distance, and provided withwhifile-trees e e. These arms pass through supports ff, which will bemore particularly hereafter described. C designates a collar or yoke,made as seen in fig. 1, or rounded at its centre, where it is secured tothe lower side of the outer portion of the tongue, and made at its lowerends horizontal, upon which blocks pg are placed. These blocks arefurnished with adjusting-holes, as seen in fig. 2. ff are supports oruprights, situated loosely upon the ends of the collar C, alongside ofthe blocks 9 g, and are made with adjusting-holes also, through whichpass the arms 0' c, as above intimated. G G designate the beams of thecultivator-teeth, the front ends of which are provided with clips orbraces, embracing the blocksgg, and secured thereto, at any distanceapart, by means of pins entering the holes in the blocks. The outer endsof these beams, on the under side, arefurnished with shanks ii, to whichare attached the shovels or teeth of the cultivator. The shanks ii areprovided with vertical slots at their lower ends, into which isinserted'one end of the curved bars or supports it h, which are fastenedtherein by keys or pins. The opposite ends of the curved bars it h aresecured to the beams G G. k k designate staples, fastened to theupperside of the beams G G, which are designed to catch into the hooks dd, on brace b of the frame A, for the purpose of throwing thecultivator-teeth up out of the way after plowing. Z Z designate thestraps or hands, secured to the upper rear ends of the beams G G, forthe purpose of receiving the feet of the driver, when located in theseat F, onthe rearbar of frame-A. J J are bails or handles,

attached to the sides of the rear ends of the beams of thecultivator-teeth, and projecting upwards, within a suitable distance ofthe driver, so as to permit of the driver operating them, in order toraise or lower the teeth.

What I claim, and desire to secure by Letters Patent, is-

1. The yoke C, secured to the under side of the tongue, and providedwith the adjusting-blocks g g, in combination with the beams G G,uprights ff, provided with adjusting-holes, double-trcc 0, arms a a, andbraces, connecting the ends of the yoke with the main frame, allconstructed, arranged, and operated in the manner and for thepurpose setforth.
